Notification settings: pick custom sounds for messages and call ringtones (#6897)

* Notification settings: pick custom sounds for messages and call ringtones (#6702)

* Feature: add notification sound settings for messages and calls

* Add sound not available banner, accessibility checks

* Fix build and Konsist convention violations

- libraries:preferences:api now uses io.element.android-compose-library
  so NotificationSound's @Immutable annotation can resolve, matching the
  pattern in libraries:matrix:api.
- Rename SoundUnavailableBannerStateProvider to
  NotificationSoundUnavailableStateProvider so the class name contains
  the parameter type as required by KonsistClassNameTest.

* Suppress LargeClass on RoomListPresenterTest

The three new sound-unavailable tests pushed the class past Detekt's
default LargeClass threshold. Matches the suppression pattern already
used on five presenter test classes under features/messages/impl/test.

* NotificationSettingsView: guard ringtone-picker launchers in inspection mode

rememberLauncherForActivityResult requires a LocalActivityResultRegistryOwner,
which Paparazzi-driven preview snapshot tests don't provide, causing
NotificationSettingsViewPreview to throw IllegalStateException for every
preview parameter. Extract the click handlers into a helper that returns a
no-op when LocalInspectionMode.current is true; the runtime path is unchanged.

* Handle unresolved notification sounds mid session

* Quality checks, refactor mid session error ui

* Suppress detekt LargeClass on NotificationSettingsPresenterTest

* Remove notification sound resilience layer, replace with file copy

* Reselect element sound option, code cleanup

* Add element fade notification sound option

* Fix new file headers

* Revert to flowOf(Unit) for announcement service

* Add ringtone picker dialog to match message selector

* Update strings in conjunction with ios

* Update test to reflect new string

* Sync strings.

* Update screenshots

* Fix test

* Remove not properly located translations.
This will be fixed in the next String sync.

* Fix test on CI
